2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2021-01-05dm: Use access methods for dev/uclass private dataSimon Glass1-4/+4
Most drivers use these access methods but a few do not. Update them. In some cases the access is not permitted, so mark those with a FIXME tag for the maintainer to check.

2020-12-14dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass1-7/+7
Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass1-2/+2
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass1-1/+1
Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-14dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-5/+5
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-25treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()Masahiro Yamada1-1/+1
Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work.

2019-01-25serial_arc: Allocate buffer for private dataAlexey Brodkin1-0/+1
Apparently we never allocated buffer for arc_serial_platdata which for some reason never caused problems when executed in nSIM. But in Qemu this causes expected problems. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-11-14serial: Remove DM_FLAG_PRE_RELOC flag in various driversBin Meng1-1/+0
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-06-01dm: Rename dev_addr..() functionsSimon Glass1-1/+1
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass1-1/+1
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2016-03-15dm: serial: Remove duplicated carriage return characterAlison Wang1-3/+0

2015-04-03serial/serial_arc: set registers address during compilationAlexey Brodkin1-2/+1
Being global variable with 0 value it falls into .bss area which we may only use after relocation to RAM. And right afetr relocation we zero .bss - effectively cleaing register address set for early console. Now with pre-set value "regs" variable is no longer in .bss and this way safely survives relocation. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

2014-02-21serial/serial_arc: switch from {read|write}l to {read|write}b accessorsAlexey Brodkin1-9/+9
This is required for proper functionality on big-endian targets. Memory-mapped registres of ARC UART are not 32-bit words but 8-bit bytes so on little-endian target either acessor (_l or _b) works fine. On big-endian only _b accessors works as expected.
